Be it a software development company or businesses that need web applications, both struggles for the same- a robust web application that’s build in secured environment. Even, in the leading companies, separate security departments are setup that take care of application security.
Professional app development standards are followed and different type of testing like- manual code review, automated testing, unit testing, integration testing and more is done, but still, sometimes, the malicious code or scripts are able to get inside the application. Right?
The popularly known attacker that has become major headache for the developers is Cross-Site Scripting (XSS). Well, XSS is not new, but, for the novice developers, it may be, so let’s take a quick look at XSS.
XSS Attacks are of Three Types:
In persistence attacks, the malicious code is sent to a website where it’s stored for specific duration of time like- message board posts, web mail messages, web chat software and pretty more. It affects the web application just by viewing the web page where vulnerable code/link is sent.
- DOM Based:
This is all about how these three attackers attacks the websites in different ways. Let’s take a glance how this Cross-site Scripting actually works.
- Disclosure of user session cookies
- Hijack the user’s session and sometimes, even take over the account
- Modify the presentation of Web content
- Redirect the user to vulnerable websites
- Disclosure of end user files and other documents
- Installation of Trojan horse programs
- Spread web worms
- Exploit intranet appliances and applications
How to protect from this malware is the next question hitting your mind? Correct? Well, you can disable such worms that’s fooling you and making your website vulnerable using HttpOnly flag. The HP Fortify tool is highly used by the developers that scan the web applications at the places where code is endangered with the attack of malwares like- XSS. Regularly, the tool enlist the points alongside description where the code is at the verge of attack, and also provide the processes to fix the security holes.
